1. Physical Properties of Aluminum

Try these first

1. 1.

   What is the atomic number of aluminum?

   Hint

   Look for how many protons aluminum has.

2. 2.

   What color is aluminum in its natural state?

   Hint

   Consider its shiny, reflective characteristic.

3. 3.

   What is the atomic number of aluminum?

   • 11
   • 12
   • 13
   • 14

   Hint

   Recall the periodic table.

4. 4.

   True or False: Aluminum has a higher density than steel.

   • True
   • False

   Hint

   Think about the weight comparisons.

5. 5.

   If aluminum has a density of 2.7 g/cm³ and several engineering applications require materials lighter than this, analyze how aluminum's properties facilitate its use in such applications.

   Hint

   Consider both structural and non-structural applications.

6. 6.

   Discuss the impact of aluminum's thermal and electrical conductivity on modern engineering applications.

   Hint

   Look at roles in electrical engineering and power distribution.
